We are just getting started
The 9P-ARCH network is pursuing next steps to better understand these syndromes & their biology
Thanks to all the families, collaborators, team members, & current funders & future potential donors who are making this all possible. Appreciate all of you! 😀 TNTurner

Gene prioritization
Using human variation + spatial transcriptomics, we identified 24 genes driving most cases of 9p deletion syndrome (83% of individuals).

We found two late-replicating regions where most structural variant breakpoints occur.
➡️ Suggests replication-based issues are a major driver of structural variant formation in 9p deletion syndrome.

Background
Until now, most work on 9p deletion & duplication syndromes relied on low-resolution methods (karyotypes, microarrays). They gave important first insights, but left many questions unanswered.
Our study is the first large-scale whole-genome sequencing (WGS) of 9p syndromes.
